BUILDING HAVING AN' OBTUSE-ANGLED OUTER CIRCUMFERENCE Filed Dec. 26, 1947 Patented Aug. 28, 1951 BUILDING HAVING AN OBTUSE-ANGLED OUTER CIRCUMFERENCE Jan van Hulst, Amsterdam, Netherlands Application December 26, 1947, Serial No 794,332 In the Netherlands July 12, 1944 Section 1, Public Law 690, August 8, 1946 Patent expires July 12, 1964 1 Claim. (01. 20 -11) 1 This invention relates to a building having a floor plan, of which the outer circumference is entirely or at least partly obtuse-angled.

Buildings with a floor plan of this kind are very uncommon. As a rule the outer circumference 5 of buildings, houses and villas comprises a number of walls which are perpendicular to each other, the floor plan being substantially .COll'lposed'of a number of interconnected rectangles.

This is due to the fact that a rectangular space presents special advantages as living, working or storage room, since the large furnishing objects, such as cupboards, beds and tables, are mostly of rectangular shape and are preferably placed in a right-angled corner or against a straight plane wall, so as to obtain a practical and economical divisionof the available room.

When both the length and width of the floor plan as a whole are ofthesame order of magnitude but the dimensions of the individual rooms relatively small by comparison, as is the case in nearly all single houses and small groups of houses under one 'roofing, an outer circumference with wall sections which are perpendicular to each other presents, however, the drawback vide a building with a floor plan, by which the above mentioned drawback is completely eliminated and a very rational division of the various rooms is realised, whilst the several advantages of the known rooms with a rectangular shape are maintained. 3 Another object of the invention is to provide a building in which all the rooms are easily accessible from a central inner space.

A further object of the invention is to provide a building in which large built-in groups of cup- 4 boards may be arranged in the rooms, in such a manner that the cupboards are easily accessible, as well from the central inner space as from the interior of the rooms.

A still further object of the invention is to pro- 4 vide separating walls between the various rooms which are all of the same length and are preferably made removable, so as to enlarge or to diminish the area of the various rooms at will.

Still further objects, advantages and special features of the invention will become evident from the following description with reference to the accompanying drawings, in which some preferred embodiments of the invention have been illustrated by way 01 example.

Fig. 1 shows a floor plan of a single dwelling house according to the invention.

Fig. 2 is a floor plan of a house having an outer circumference in the shape of a regular dodecagon.

Fig. 3 is a similar floor plan which is also based upon a regular dodecagon, but in which two parallel sides thereof are longer than the other ones.

Fig. 4 is a floor plan of a house having an outer circumference in the shape of a regular octagon.

Fig. 5 shows a similar floor plan based upon a regular octagon, but in which two parallel sides thereof are enlarged.

Referring to Fig. 1, the building comprises an outer circumferential wall, generallyindicated by A, of which the straight wall portions or sections include obtuse angles, and a central inner space E bordered by straight wall portions or sections of. the same number as and parallel to the wall sections of the outerlboundingwall A. Between the outer bounding wall and the said inner space thus an annular space is formed which is destined for the rooms. The separating walls C between the rooms do not terminate in the angular points D of the outer bounding wall, but are traced perpendicularly to the outer Wall sections. Consequently these separating walls are also perpendicular to the corresponding wall sections of the inner space E. A room may thus be defined by the points I, 2, 3, D and 4. It follows that each room has always two right-angled corners along the outer bounding wall. For a bedroom beds may be placed in the said corners, whilst along the outer wall suiiicient space remains for placing other furniture. In each room a considerable part of the outer wall is available, so that the room may be easily provided with large windows and/or outer doors. The walls of the inner space B are provided with the entrance doors to the various rooms and comequently each section of this interior wall has at least the Width of a door opening.

In the right-angled corners formed between the separating walls C and the sections of the interior wall built-in cupboard structure may be arranged. These cupboards are accessible, as well from the inner space B as from the interior of the rooms by the door openings illustrated.

In Fig. 1 the separating wallsC are all of the same length, so that a great variation in the number and size of the rooms to be formed is possible, when these walls are made removable.

The inner space B may be lit from above and comprises a staircase E leading to a garret room below the roof. The central heating may be arpart the first 'floor of the building. latter figure, the outer wall A has the 'wall portions N, N-thereof meeting atobtuseanglesB, and in one respect theffigure resembles .the-tplan ranged along the outer walls, Whilst the electric installation is preferably mounted as much as possible along the inner space.

The floor plans according to Figs. 2-5 display certain modifications. .Also in these plans the inner space B'has in each case thesame number of wall sections as the outer circumference, as for example in Fig. 2, outer wall A has portions E E etc. and inner wall portions FF, etc., while the inner and outer wall sectionsare parallel-to each other. The outer wall portions E ,E meet at obtuse angles D D and the partition walls C C separate the rooms. The area destined for the latter rooms also comprises a regular. concatenation of rectangles and quadrangles composed of two right-angled triangles (a, .b, c, d, and (2,0, e, f) the cupboard structure G, G beinglocated in certain inner right-angled corners of the rooms. In the polygonal outlined by theouter wall floor plan according to Fig 3 A there is;.a large. rectangularistorageqroom F which may be used as motor garage. ln thisxfigure; the outer :polygonal wallA has the flat outer wall portions -H meeting toform the obtuse angles D etc... while the partitions C C meet at right angles with: intermediate portionsof certain of these wall portionsandextend inwardly to inner wall:sec

.tions.;I which define;inner,space B -and include ..certaintr ight;angled inner corners in the. resulting .rooms .into which cupboard: structure K, K are built in order to form partof the building. .An-

rotherifeature.disclosed in the view is-that the two parallel outer wall =portionsH,:I-I', are long- .zer than the other wall-portions etc.,.so that the polygonal form of the plan as a whole is lat-z. rerally elongated.

"In Fig. 4, theouter wallA? also'has the individual wall portionsJ, J thereof joined at obtuse angles D while the inner wall portions L, L are parallel thereto and define intermediate space:.B

"The partition walls C meetwithintermediate portions of the outer wall portions J at right angles-thereto and certain of the resulting rooms areprovded with the'built-in rectangular :cup-

"board structures M, M in inner right .angled corners thereof. In Fig. 5 the left hand. part illustrates the-ground floor and the right hand In the of Fig. 3, namely, in that the two opposite parallel -W811 portions N, N- are longer: than the :other Number 4 wall portions N, N. The inner wall portions 0, O are parallel to the outer wall portions N, N etc., and defining the inner central chamber 3, while partition walls O, C etc., meet with intermediate Portions of the outer wall portions N, N etc., to form right angles therewith. Certain of the rooms also have the built-in cupboard structures .P in at least one of the inner right angled corners thereof.

In -allof .theforms of the building, the cupboardstructures are accessible in the rooms con- .taining tthem .and also from the central space B,B', B etc., within the inner wall of the building involved. :In ,addition, the partition walls at alltimes connect with the inner Wall at angu- -lar,junctions.of the inner wall portions and with intermediate portions of the outer wall portions at right angles to the latter.

Manifestly, other variations than those shown and described may be resorted to, and parts and 'features may be modified or used withoutothers within the scope of theappended claim.

WhatI claim is:

A polygonal building, comprising-in combination, an outerwall composed of .a series of flat outer wall portions meeting toform' angular junctions; anrinnerwall composed ofa-series of flat inner wall portions meeting to form angularjunctions,.each of said inner wall portions being parallel to one of said outer Wall portions so that said walls define a substantially annular enclosure; and awplurality of partition walls dividing said annular enclosure into aseries of-adjoining rooms, each of said partition .Walls forming .a right angle with an intermediate portion of an outer walland each of said partition walls'at; its inner end joining said inner WEI-1123,13 an angular junction thereof and. being normal vto, one of said inner wall 7 portionsforming said junction.
